A two-stage application device is disclosed for installing a screen protector on a display screen of a screen-mounted device. The application device includes a base, a first actuating lever, and a second actuating lever. The base includes an accommodation and a support, wherein the support defines first grooves and second grooves. The first actuating lever has first controlled pivot portions guided and limited by the first grooves, a first pressing portion, a first arm, and a body with a positioning protrusion. The second actuating lever has second controlled pivot portions guided and limited by the second grooves, a second pressing portion, a second arm, and a body. A kit is also disclosed for protecting a display screen of a screen-mounted device, which includes a two-stage application device, and at least one screen protector including a protective film with at least one adhesive layer, and a backing sheet.

Systems and films for protecting surfaces of various substrates, including electronic devices, such as portable electronic devices, include a liner with a strip liner and a main liner. The strip liner, which covers a small strip of adhesive on the back side of a protective film, is configured to be removed before the main liner. With the small strip of adhesive exposed, the protective film may be aligned with a substrate and, if necessary, removed from the substrates and repositioned thereon. Thereafter, the main liner may be removed to enable complete application of the protective film to the substrate. Methods for securing protective films to substrates are also disclosed.

A tool for applying tint film to an inside window surface of an automobile has a unitary body with a handle portion and a downwardly depending neck extending from the handle portion to an elongate blade supporting portion. The blade supporting portion includes a bottom zone extending to a chamfered distal end. A flexible blade is attached to the bottom zone and the distal end of the blade supporting portion. The flexible blade includes a forwardmost portion that extends beyond the distal end of the blade supporting portion.

Devices, methods and systems disclosed herein relate to the application of a protective film on a surface of an electronic device that instantly reduces air bubbles and eliminates the waiting time usually required when using a wet fluid solution. In one embodiment, a roller device may include a carriage or housing and one or more rollers coupled or integrated with the housing, configured to apply a protective material to a surface of the electronic device in a first orientation, and configured to function as a device stand in a second orientation. In addition or alternatively, a roller guide apparatus and/or a wedge may be utilized to assist the roller device in applying the protective material to the surface of the electronic device.

A laminating apparatus for a curved screen including a base, an elastic component, a backing plate, and a flexible pressing mold, where the backing plate is arranged above the base, the elastic component is connected to the backing plate, the flexible pressing mold covers the backing plate, and a top of the flexible pressing mold is arranged as a curved surface adapted to a shape of a screen; and the base includes a main body and two side beams connected to two sides of the main body, the side beams are higher than the main body in a vertical direction, the side beams are provided with grooves and supporting parts extending along length directions of respective side beams, and two sides of the flexible pressing mold extend outward to cover the supporting parts and reach into the grooves.

A tape attaching method for attaching a tape to a workpiece includes a placing step of placing the workpiece with respect to the tape, which has a base material and an adhesive layer on the base material, in such a manner that the adhesive layer is in contact with an attached face of the workpiece, and a close contact step of causing, after the placing step is performed, a ball to roll in contact with the base material of the tape, thereby to bring the tape in close contact with the workpiece.

An apparatus and/or method for installing a screen protector on an electronic device, for example using a wet application process. The apparatus includes a support member for supporting the electronic device and a clamp mechanism for clamping the electronic device in a fixed position on the support member. A tack assembly is used to tack the screen protector to the electronic device. The tack assembly includes an actuator that, once actuated, causes a tack member to apply a force onto the screen protector which tacks the screen protector to the electronic device and prevents misalignment. Finally, a roller assembly is actuated so that a roller member moves across the screen protector to bond the screen protector to the electronic device and remove any excess liquid that may exist between the screen protector and the electronic device.

A method for laminating a protective screen onto a flexible display support, notably an electronic tile, includes the following steps bringing a protective screen and a display support progressively into contact by using an elastically deformable punch until a maximum area of contact between the protective screen and the display support is achieved in a configuration in which the assembly formed by the protective screen and the display support is fully laminated. The external surface of the punch has a three-dimensional shape substantially equal to that of the display support.

A tool for applying tint film to an inside window surface of an automobile has a unitary body with a handle portion and a downwardly depending neck extending from the handle portion to an elongate blade supporting portion. The blade supporting portion includes a bottom zone extending to a chamfered distal end. A flexible blade is attached to the bottom zone and the distal end of the blade supporting portion. The flexible blade includes a forwardmost portion that extends beyond the distal end of the blade supporting portion.

Disclosed herein is a screen protector assembly and a screen protector applicator comprising a screen protector assembly and an applicator tray, the screen protector assembly comprising a cover layer, a screen protector layer and a retention layer, wherein: the cover layer is bonded on a first side of the screen protector layer by a first glue layer provided on the screen protector layer; the retention layer is bonded on a second side of the screen protector by a second glue layer provided on the retention layer; and an interlayer is provided between the retention layer and the screen protector layer. The screen protector applicator has a simple structure, and can store and protect the screen protector assembly before application of the screen protector layer to the screen. In the process of screen protector application, the operation method is simple and convenient.
